ZWC

Incorporated several fixes provided by the community: A fix for Bug 98570 ensures that the "arrange by day" boundaries adapt to Daylight Savings Time. Another fix addresses a potential TypeError in ZmComposeView.prototype.enableInputs. Thank you to our contributors!

ZCO

To align with the Out of Office message options available through the Web interface, ZCO now supports excluding replies for external users.

ZCO

Run Filters is now supported. The user may select any Zimbra Email Filter to run on-demand. Feedback is provided while the rule is run on a selected folder.

Note: The filter is run on the Zimbra server, so the client must be online, and changes for affected messages need to synchronize to the Outlook client before they are visible.

ZCO

ZCO Database Automatic Compaction: To maintain performance, large databases will automatically be compacted to resolve fragmentation and reduce size.

ZCO

The location for ZCO documentation has changed. If you had bookmarked zco-docs, update your bookmark to point to zm-windows-comp.

NG Backup

Added a new force_as_external_restore option to the External Restore feature to improve Disaster Recovery usability.

NG Backup

Improved Backup Purge to ignore errors triggered by the original item having an invalid locator field.

The EmptyFolderContent EAS command is now only supported for the /Trash folder.

Fixed Issues

Fixed a potential NullPointerException that could occur when handling password change requests.

ZWC

In the Admin Console, the setting for zimbraLdapGentimeFractionalSecondsEnabled is now accounted for when showing zimbraCreateTimestamp, zimbraLastLogonTimestamp, zimbraVersionCheckLastAttempt, and zimbraVersionCheckLastSuccess. Previously, those values were truncated at the second.

Zimbra Drive

Fixed a bug that could cause documents saved to Drive from an email to become uneditable by Docs.

Zimbra Drive

Zimbra Drive would display a "Wrong Server" warning for users in a multi-node environment unless they were hosted on the proxy node. This was fixed by ensuring that proxy configuration files are properly generated on all nodes at startup.

Zimbra Connect

Fixed a bug that could cause the "Conversation Created" message to be misplaced.

Fixed a bug that could increase disk usage during the HSM operation.

HSM

Applying the HSM policy when the source volume contained Drive files reported filename errors in the log and did not move Drive files

On profiles that have multiple stores mounted (e.g., delegated stores), Auto-Compaction is engaged for each store, but repeats compaction of the primary ZDB instead of the mounted ZDBs.

The Run Filter feature is available in English only. Localization will be provided in the next patch release.

ZCO
